Offer an autocomplete version

I've created an MR for the patches and also rerolled. Please find the attached patch with the reroll so is compatible with the latest version.

Attached one more patch because I've accidentally uploaded a wrong one.

Now it works fine, every term selection is an autocomplete form element. PLease review, thanks!

Updated the patch by adding accessCheck for resolving the following error in D10 setup:

Drupal\Core\Entity\Query\QueryException: Entity queries must explicitly set whether the query should be access checked or not. See Drupal\Core\Entity\Query\QueryInterface::accessCheck(). in Drupal\Core\Entity\Query\Sql\Query->prepare() (line 162 of /var/www/html/docroot/core/lib/Drupal/Core/Entity/Query/Sql/Query.php).

Please ignore the patch added in #11. Adding an updated patch for D10, 2.0.x version
